Description
Die Erfindung bezeichnet eine Arretierung eines Akkumulatormoduls, welches vorzugsweise in Elektrohandwerkzeugmaschinen wie Kombihämmer, Bohrschrauber etc. einschiebbar ist.The invention relates to a lock an accumulator module, which is preferably used in electrical hand machine tools like combi hammers, screwdrivers etc. can be inserted.

Die Aufgabe der Erfindung besteht in der Realisierung einer ergonomischen Arretierung eines Akkumulatormoduls.The object of the invention is in the implementation of an ergonomic locking of a battery module.
Die Aufgabe wird im Wesentlichen durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The task essentially becomes by the characteristics of the independent Expectations solved. Advantageous further developments result from the subclaims.
Im Wesentlichen weist ein in ein Gehäuseteil einer Handwerkzeugmaschine längs einer Einschubrichtung einschiebbarer Akkumulatormodul zwei an gegenüberliegenden Seiten eines Modulgehäuses angeordnete, gegeneinander sowie quer zur Einschubrichtung des Akkumulatormoduls orientierte und mit zumindest einer Blattfeder nach aussen vorgespannte Arretierhaken auf, die mit Fingerpressflächen verbunden sind, welche zwischen zwei Fingern einer Hand von einer Ruheposition in eine Entarretierungsposition zusammendrückbar sind, wobei zumindest eine Blattfeder bi-konvex ausgebildet ist und zwischen der Ruheposition und der Entarretierungsposition eine lokales Kraftmaximum ausbildet.Essentially, one points to one Part of a housing Hand machine tool lengthways one insertion direction insertable accumulator module two on opposite Sides of a module housing, against each other and across the insertion direction of the battery module oriented and biased outwards with at least one leaf spring Locking hooks, which are connected to finger press surfaces, which between two fingers of one hand from a resting position to one Unlocking position are compressible, at least a leaf spring is bi-convex and between the rest position and the unlocking position forms a local force maximum.
Durch die bi-konvexe Ausbildung wird bei einer Deformation der Blattfeder auf Grund des Beulverhaltens eine nichtlineare Federcharakteristik erzeugt, die vor einem degressiven Kurventeil mit einem lokalen Kraftminimum notwendig ein lokales Kraftmaximum ausbildet. Somit ist die in der Entarretierungsposition notwendige Haltekraft geringer als beim Übergang von der Ruheposition zur Entarretierungsposition, wodurch die Finger spürbar entlastet werden. Zudem ist das Erreichen der Entarretierungsposition durch das vom Nutzer fühlbare Einsacken des Arretierhakens (Klick – Druckpunkt) nach Überwindung der lokalen Versteifung ein vom Nutzer registrierbares Feedback.Due to the bi-convex formation if the leaf spring is deformed due to the buckling behavior produces a non-linear spring characteristic, which before a degressive Part of the curve with a local force minimum requires a local force maximum formed. So that is necessary in the unlocking position Holding force less than at the transition from the rest position to the unlocking position, causing the fingers noticeable be relieved. In addition, the unlocking position is reached through what the user can feel Bag the locking hook (click - pressure point) after overcoming the local stiffening a feedback that can be registered by the user.
Vorteilhaft ist die Entarretierungsposition energetisch labil ausgebildet, d.h. das zugeordnete Potential weist kein lokales Energieminimum auf, wodurch der Arretierhaken trotz der verringerten Haltkraft selbständig zurück zur Ruheposition getrieben wird.The unlocking position is advantageous energetically unstable, i.e. has the assigned potential no local energy minimum, causing the locking hook despite the reduced holding force is automatically driven back to the rest position.
Vorteilhaft ist die Blattfeder in sich dämpfungsarm, bspw. aus dünnen Federstahl, ausgeführt, wodurch von der Blattfeder im degressiven Übergang von der Ruheposition zu der Entarretierungsposition ein deutlich hörbares Klick – Geräusch erzeugt wird.The leaf spring is advantageous in low damping, e.g. from thin Spring steel, executed, whereby from the leaf spring in the degressive transition from the rest position a clearly audible click sound is generated at the unlocking position becomes.
Vorteilhaft sind beide Arretierhaken mit je einer bi-konvex ausgebildeten Blattfeder gleicher Federcharakteristik verbunden, wodurch zur Kraftübertragung zwischen den beiden Blattfedern das Modulgehäuse zwischenschaltbar ist.Both locking hooks are advantageous each with a bi-convex leaf spring with the same spring characteristic connected, causing power transmission the module housing can be interposed between the two leaf springs.
Vorteilhaft erstreckt sich die Blattfeder über den Längenbereich der Fingerpressfläche, wodurch dieser Längenbereich zur Ausbildung einer grossflächigen bi-konvexen Fläche nutzbar ist, um den degressiven Kurventeil zu vergrössern.The leaf spring advantageously extends over the length range the finger press surface, making this length range to form a large area bi-convex surface can be used to enlarge the degressive part of the curve.
